+**Use squash merge.**
+Upon merging, this will automatically build the CLI and create a GitHub release.
+You still need to manually publish the cargo crate.

+$ git pull

+_Binstall is a tool to fetch and install Rust-based executables as binaries. It aims to be a drop-in replacement for `cargo install` in most cases. Install it today with `cargo install cargo-binstall`, from the binaries below, or if you already have it, upgrade with `cargo binstall cargo-binstall`._
